The following table shows the endurance results for FSG. Find the point difference of the team that placed 5th from the team that placed 2nd. Calculate to 2 decimals.

Team A and team B are both EV teams and compete in Acceleration. Team A’s acceleration is described by the function: a(t) = 17*t, 0<t<0.5, a(t) = 8.5, t>0.5. Team B’s acceleration is described by the function: a(t) = 8.3, t>0. Variable t refers to the time in seconds since starting the vehicle. Calculate the difference of team A’s points from team B’s points to the 1st decimal. Assume no other teams competed in EV Acceleration.

Choose the false statement(s)

The TS Accumulator Current and Voltage measurements sent by a status message to the data logger, if multiplied together, can have a higher result than the Power measurement sent to the data logger by the same status message.

The team is responsible for keeping any equipment used for timing of the runs during the FSG Competition in good condition.

If a bent tube is used anywhere in the primary structure ,other than the front and main roll hoops, an additional tube must be attached to support it, the attachment point of which must be at the tube’s highest point (in relation to the ground), if the straight line connecting both ends is horizontal (again, in relation to the ground).

A body with mass M with speed V hits a still body with double the mass. If the time of the collision was dt, then the mean value of the force applied from one body to the other is equal to:

4MV/3dt

2MV/dt

MV/(2dt)

The following graph shows the speeds of bodies (1) and (2) in relation to time, before and after their head-on collision. The collision is:

Elastic

Inelastic

Plastic

Perfectly plastic

In the following figure, the body with mass m2 = 5kg on the horizontal surface with friction coefficient μ=0.3 is attached to a pulley with mass M=2kg and radius R = 0.5m. On the other side of the pulley, a body with mass m1 = 2kg is suspended in the air. Find the acceleration of the body with mass m1. Assume the pulley is a perfect disc, and g=9.81m/s^2.

A vehicle consumes 30 liters of fuel per hour, delivering 75 kW of power to the wheels. If the fuel has a heating value of 40000 kJ/kg and a density of 0.6 g/cm^3, what’s the efficiency of the vehicle? Answer in percentage, rounded to the 1st decimal.

What was the total amount of penalties handed out, judging only by the timetable for FSG’s endurance below? Round to 2 decimals in seconds. Assume AMZ Electric didn’t receive any penalties for whatever reason.

A ramp in an amusement park is frictionless. A smooth object slides down the ramp and comes down through a height h=6m What distance d is necessary to stop the object on the flat track if the coefficient of friction μ=0,6 ? Answer in meters in the first decimal.

To prevent vehicle roll during cornerning, the roll center has to be:

At 2❄3 of the vehicle Center of Gravity height

At the level of the vehicle CoG

At 1❄3 of the unsprung mass CoG height

At the level of the sprung mass CoG

Below the road surface

Calculate the Output S3S2S1S0¬ of the following digital circuit. A3A2A1A0=1011 B3B2B1B0=0101 If the system overflows, add one more bit as 1 to the most significant bit (5th), otherwise add 0. [Give your answer in binary].

Sand is continuously thrown into a moving plane as shown in the picture. The plane has a constant speed u as force F is applied to keep it constant. Calculate the power , where W is the work from force F when dK/dt = 3567 J/s. [Give your answer in KJ/s in 2 decimals]

Choose the false statements:

If a PCB has a TS and a LV area, only the connectors on the TS area are required to be rated for the max TS voltage.

Nord-Lock X-series wedge-lock washers may be used as securing fastener devices.

DVs using an AIP made out of alternative materials do not have to repeat an IA test for the given IA assembly, using the actual similar materials as the intended chassis. If the AID of the older car had been approved previously, this will remain valid for FSG 2020 as long as the whole IA assembly is the same.

All electrical safety items must have a withstand voltage of at least the max. TS voltage.

Choose the true statements:

Despite the bonus fashion points awarded for them, wearing Crocs (classic clogs) is not allowed while working on the vehicle.

Concerning the max points awarded in Engineering Design Event, the difference between ‘Vehicle Performance’ and ‘Mechanical/Structural Engineering’’ as a CV team is equal to the same difference as a DV team.

A diode-zener sub circuit can be included in the device to boost sensing performance.

Every single cell must be able to withstand accelerations of at least 196.133 m / (s^2) in all directions.

Your team set the fastest lap time at the Autocross event with a time of 75seconds on your first and only run. However, on the final scoring sheet your team is listed in fifth place with 73.8 out of 100 points, while the new winner of the event has an uncorrected elapsed time of 84seconds.
